Cavanagh (from Irish: Cabhanach, meaning "abounding in hollows") is a townland in the civil parish of Tomregan, County Cavan, Ireland. It lies within the former barony of Tullyhaw.
The townland derives its name from the low-lying areas between its drumlin hills. The oldest surviving mention of the name is in the 1609 Ulster Plantation map where it is spelled ‘Cavan’.
Cavanagh is bounded on the north by Mullaghduff townland, on the east by Cranaghan townland, on the south by Cloncollow townland and on the west by Agharaskilly townland. Its chief geographical features are Lough Rud and a drumlin hill reaching to 219 feet (67 m) above sea-level.
Cavanagh is traversed by the N87 road (Ireland), Cavanagh lane and the disused Cavan and Leitrim Railway.
The townland covers 275 statute acres, including 9 acres (36,000 m2) of water. It formed part of the Manor of Calva which was granted to Walter Talbot in 1610 as part of the Plantation of Ulster.
The Tithe Applotment Books for 1827 list the following tithepayers in the townland- Patterson, Armstrong, Core, Taylor, Hacket.
The Ordnance Survey Name Books for 1836 give the following description of the townland- "Cabhanach, 'abounding in hollows'. Belongs to Montgomery. Tithe 10d per arable acre. 90 acres of bog and pasture. Produces oats and potatoes. Soil light. Houses are built of mud. The inhabitants are mostly Protestants."
The 1841 Census of Ireland gives a population of 74 in Cavanagh, of which 32 were males and 42 were females, with 16 houses.
The 1851 Census of Ireland gives a population of 51, a decrease of 23 on the 1841 figure, due to the intervening Irish Famine of 1845–47, of which 25 were males and 26 were females, with 11 houses, of which one was uninhabited.
Griffith's Valuation of 1857 lists the landlord of the townland as Vernon & the tenants as Faris, Taylor, Kells, Netterfield, Pattison, Armstrong and Stokes.
